The ability of skin to retain water and its hydration are essential for both the appearance and function of the skin barrier. Dry skin occurs when natural hydration mechanisms are impaired, accompanied by a loss of elasticity, scaling and an unpleasant feeling of tightness. The aim of this article is to explain the mechanisms of skin hydration and describe the properties of moisturizing cosmetic products. The article discusses the mechanisms of action and examples of cosmetic humectants, emollients, and occlusives that prevent transepidermal water loss. Moisturizing cosmetics containing these ingredients are therefore essential for restoring and maintaining skin hydration. Knowledge of the composition and function of dermocosmetics can assist not only in selecting suitable products but also in educating users/patients on their proper use.
